!3DGraphic/!Help
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

3D Graphics: A New Dimension By Dave Acton Run this application to open a directory containing the programs from the first part of the series on 3D graphics. Before running any of these programs, double-click on ThisDir to set the CSD correctly. 3Ddemo1 and 3Ddemo2 show two different views of the virtual world created by the series. When the programs are run, they create 36 frames before displaying rotating views of three houses in a landscape. Both programs access the files in the Objects directory, as well as the routines in the program 3Dprocs; running 3Dprocs itself will produce an error as it is a library program. PerspDemo demonstrates perspective. A rotating box is displayed; moving the mouse up and down will alter the distance to the box, and moving the mouse left and right will alter the scale of the box. For more details, see page 90 in the magazine. � Copyright BBC Acorn User 1993
